Antenna system

Abstract

An antenna system comprises at least one antenna, a feeding line and a cable guide for a line not feeding the at least one antenna. The at least one antenna has a feeding portion to which the feeding line is assigned. The cable guide has an opening that is provided in the feeding portion.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 
     
       1. An antenna system comprising at least one antenna, a feeding line and a cable guide for a line not feeding the at least one antenna, wherein the at least one antenna has a feeding portion to which the feeding line is assigned, and wherein the cable guide has an opening that is provided in the feeding portion, wherein the opening is located at a lateral side of the feeding portion. 
     
     
       2. The antenna system according to  claim 1 , wherein the feeding portion has an axial end to which the feeding line is connected. 
     
     
       3. The antenna system according to  claim 1 , wherein the opening has a center axis that is inclined with respect to the lateral side of the feeding portion by an inclination angle. 
     
     
       4. The antenna system according to  claim 1 , wherein the at least one antenna has a flared horn portion and a center axis, wherein the opening is orientated in the feeding portion such that the line guided through the opening runs substantially along the center axis in the space limited by the flared horn portion. 
     
     
       5. The antenna system according to  claim 4 , wherein the center axis relates to a rotationally symmetric axis of the at least one antenna. 
     
     
       6. The antenna system according to  claim 1 , wherein the feeding portion comprises a waveguide section and a feed point. 
     
     
       7. The antenna system according to  claim 6 , wherein the waveguide section comprises an electromagnetically conductive section. 
     
     
       8. The antenna system according to  claim 7 , wherein the opening is provided in the electromagnetically conductive section. 
     
     
       9. The antenna system according to  claim 7 , wherein the electromagnetically conductive section merges partially into a flared horn portion of the at least one antenna. 
     
     
       10. The antenna system according to  claim 1 , wherein the cable guide has several openings for several lines. 
     
     
       11. The antenna system according to  claim 1 , wherein the at least one antenna is a coaxial horn antenna. 
     
     
       12. The antenna system according to  claim 1 , wherein the antenna system relates to an omnidirectional antenna system, wherein the at least one antenna is an omnidirectional antenna. 
     
     
       13. The antenna system according to  claim 1 , wherein the antenna system has a first antenna and a second antenna which are stacked over one another. 
     
     
       14. The antenna system according to  claim 13 , wherein the second antenna is a biconical antenna. 
     
     
       15. An antenna system comprising:
 at least one antenna; 
 a feeding line; and 
 a cable guide for a line not feeding the at least one antenna, 
 wherein the at least one antenna has a feeding portion to which the feeding line is assigned, wherein the cable guide has an opening that is provided in the feeding portion, wherein the at least one antenna has a flared horn portion and a center axis, and wherein the opening is orientated in the feeding portion such that the line guided through the opening runs substantially along the center axis in the space limited by the flared horn portion. 
 
     
     
       16. The antenna system according to  claim 15 , wherein the center axis relates to a rotationally symmetric axis of the at least one antenna. 
     
     
       17. An antenna system comprising at least one antenna, a feeding line and a cable guide for a line not feeding the at least one antenna, wherein the at least one antenna has a feeding portion to which the feeding line is assigned, and wherein the cable guide has an opening that is provided in the feeding portion, wherein the feeding portion comprises a waveguide section and a feed point, wherein the waveguide section comprises an electromagnetically conductive section, and wherein the electromagnetically conductive section merges partially into a flared horn portion of the at least one antenna.
